They get used interchangeably, but a estimate and an invoice do very different jobs — and mixing them up is how disputes start.
Different documents, different jobs. Mixing them up is how price disputes and late payments start. Here's what each one does in United States.
A estimate is what you send before doing the work — your price for the scope you've described. Set it out clearly so the client knows exactly what is and isn't included.
The invoice is what gets you paid once the work's done. In United States it needs your EIN, Sales Tax shown separately (Varies by state (0–10%+)), an invoice number, and a clear total in USD.
Estimate first to win the job, then invoice the moment it's finished. UteQuote produces either one by voice in seconds, so there's no reason to let paperwork slow you down.
An estimate is an approximation, not a fixed offer, so it generally isn't binding. Communicate any significant change before doing the work.
A Sales Tax invoice includes the specific fields IRS requires — like your EIN and Sales Tax shown separately. If you're Sales Tax-registered, that's what you issue.
UteQuote turns a quick voice note into a Professional invoices ready for your accountant estimate or invoice in seconds.
